Description

PIN-TYPE LIFTING FRAME AND DERRICK INSTALLATION METHOD USING THE PIN-TYPE LIFTING FRAME}

The present invention relates to a derrick installation method using a pin-type lifting frame and a pin-type lifting frame for lifting a derrick assembled on the ground to be installed on a drill floor of a drill ship.

Generally, cranes are used for lifting in the work place or workshop where the object to be lifted is handled.

If the crane is used in a shipyard, the crane is a lifting object, which is a ground crane for lifting a block drying structure or a ship building block for assembling the hull, and a crane boom extends to the ground while floating at sea to lift the lifting target. Floating cranes that can be lifted.

Meanwhile, as the industry develops, the use of global resources such as petroleum is gradually increasing. Accordingly, stable production and supply of crude oil has emerged as an important problem. Accordingly, offshore structures such as drilling vessels with drilling equipment suitable for the development of subsea oil fields have been developed.

Such subsea drilling using marine structures can be used for rigs, rigid platforms, etc. for subsea drilling for underwater drilling with anchorage at sea using a mooring device.

Drill ships, semi-submersible rigs, TLP (Tension Leg Platform), and production storage vessels have been recently developed with hulls that can be drilled and equipped with self-propelled drilling rigs. These production storage vessels include offshore oil-drilling platforms, floating production storage offloading (FPSO), crude oil drilling vessels, gas drilling vessels and floating liquefied gas storage vessels (LNG FSRU: LNG). Floating Production Storage Offloading).

As a background technology of the invention, for example, as shown in Fig. 1 and described in the following patent document, a jig for transporting a derrick structure using an offshore crane is disclosed.

The patent document discloses a technical idea of lifting a derrick structure 2 using an offshore crane 1 and then transporting it directly to a desired place.

However, the idea disclosed in the patent document only lifts a derrick structure 2, that is, a frame structure made of pillars, beams, and the like, and a protective wall and a vee-door added to the derrick structure 2. And other derrick-related equipment (e.g. winch connection members, deadline anchors, top drives, etc.) are not lifted in bulk.

That is, the patent document is provided with a square ring lift frame (3) for lifting the derrick structure (2), the square ring lift frame (3) is formed to wrap around the derrick structure (2), such as a protective wall In the case of a pre-mounted derrick structure, interference between the rectangular ring lift frame 3 and the protective wall is generated, which makes it difficult to attach the rectangular ring lift frame 3.

In addition, when all the derrick-related equipment is installed in the derrick structure 2 and lifted, the square ring lift frame 3 may be made stronger and larger, which may increase the weight of the square ring lift frame 3 itself. It may have a disadvantage.

In addition, since the patent document uses the marine crane 1, the derrick structure 2 together with the time to mount the square ring lift frame 3 to the marine crane 1, and the mounted square ring lift frame 3, respectively. By using the offshore crane (1) during the lifting time, the use time of the offshore crane (1) is relatively long, and consequently, the offshore crane (1) in comparison with the use of other land cranes and the offshore crane (1) in the shipyard. The utilization of the crane devices within the relatively large, there is a disadvantage that the mounting or installation costs are relatively high.

In addition, since the square ring lift frame 3 is set to be in close contact with the derrick structure 2, if there is a manufacturing error in the derrick structure 2, the square ring lift frame 3 corresponds to the manufacturing error. It is difficult to change and adjust the assembly state, which causes welding of the secondary structure to match the error between the square ring lift frame 3 and the derrick structure when the square ring lift frame 3 is mounted on the derrick structure 2. Or there are many difficulties such as additional work occurs at the height of the height, such as cutting.

In particular, the size and weight of the derrick structure 2 can be increased or the derrick-related installations can be collectively placed on the ground according to the limited shipyard and crane resources and the use of the square ring lift frame 3 which is relatively heavy. It is difficult to assemble and install on the drill floor.
